NeoNebulous 7 was a Super Smash Bros. Melee regional tournament held by Hectohertz, emilywaves, $LED, and RUSH in New York, New York, on March 29th, 2015. The tournament originally gained hype as it hosted two rounds of The Melee Games, a collegiate championship. As Leffen was coming in to see family, the tournament garnered even more excitement, building up to become the largest Nebulous at this point, with 171 people. This surpassed the 123 (or so) people at Super Nebulous 2.

The tournament itself was a major success, running round robin pools as well as three different brackets in a bit under 10 hours. It also became the largest doubles tournament at Nebulous. Commentary in top 8 was done by Prog and Hazz for the first time since the RoM period back in 2010.
